I have cloned Windows 11 ver. 22H2 (64-bit) installed initially on my HP Elitebook 840 G9 with Clonezilla. This notebook has NVMe with 512 GB capacity. Yet I use this notebook with Linux and have removed Windows installation.

In order to make UEFI/BIOS updates on this notebook I must replay a Windows installtion to do it.

My thought is that maybe I can replay image created from NVMe with Clonezilla to a USB stick (1 TB to be shure) and boot/use Windows from this USB stick.

Is that possible?

  • No, not possible. And a bootable USB stick with some FreeDOS or similar bootloader done with Rufus should be enough to boot once and update the firmware.

  • Try the Linux utilities described in the article Flashing BIOS from Linux. If this fails, try Creating a FreeDOS bootable USB stick to upgrade BIOS. Let me know which one worked for you.

  • @harrymc - I didn't know or I forgot about the possibility of upgrading BIOS/UEFI from inside Linux with fwupd-tool. Now i have current bios UEFI: HP v: U76 Ver. 01.07.00 date: 03/23/2023 (installed from replayed Windows 11). When a new bios appears for my model I will try with your suggestions or with fwupd.
